A meaningful SINR expression can be written out by dividing the useful signal power from (REF ) by the sum of the interference and the noise powers (from (REF ), and (REF )) [1]}.
Note that the interference component is comprised of the estimation error term and the signal powers of other users who have also transmitted in the same RE.
SINR can thus be calculated as in (REF ) for all users.
For MMSE/LCMMSE, the corresponding SINR can be calculated by plugging in the channel estimates as detailed in Theorem REF .
